Drilling Confirms High-Grade Secondary Enrichment Zone within Large Porphyry System

Toronto – April 24, 2025: AbraSilver Resource Corp. (TSX: ABRA; OTCQX: ABBRF) (“AbraSilver” or the “Company”) is pleased to report assay results from the ongoing drill program at the La Coipita copper-gold-molybdenum project (“La Coipita” or the “Project”) located in the San Juan Province of Argentina. The drill program is fully funded and operated by a subsidiary of Teck Resources Limited (“Teck”) under the terms of the earn-in and joint venture agreement, as per the Company’s news release dated January 22, 2024.

The assay results from drillhole DDH-LC25-006 have confirmed a significant intercept of high-grade copper mineralization, representing a new discovery including a well-developed secondary enrichment zone, within a large-scale porphyry system.   

Key Results - Hole DDH-LC25-006:

• 114 metres (“m”) grading 0.70% Cu, 0.07 g/t Au and 81 ppm Mo, from 410 m to 524 m down-hole depth, interpreted as a secondary enrichment zone.
  • Including a higher-grade interval of 20 m at 1.03% Cu, 0.08 g/t Au and 71 ppm Mo, from 412 m to 432 m depth.
• 98 m grading 0.55% Cu, 0.10 g/t Au and 143 ppm Mo, from 524 m to 622 m, interpreted as hypogene porphyry mineralization
• 409 m grading 0.25% Cu, 0.06 g/t Au and 37 ppm Mo from 622 m to 1,031 m, corresponding to a high-sulphidation epithermal overprinting zone.
• Combined these intercepts comprise 621 m grading 0.38% Cu, 0.07 g/t Au and 62 ppm Mo, from 410 m to 1,031 m demonstrating the scale of the mineralized system.   

Additional Drilling Progress:

• Hole DDH-LC25-007, located approximately 500m east of DDH-LC25-006, was completed to a depth of 846.1m and has intercepted two separate secondary enrichment zones between 40 – 275 m and 422 – 593 m, followed by a deeper zone interpreted to contain hypogene mineralization.   Assays for this hole are pending. 
• Hole DDH-LC25-008, located approximately ~500m north of DDH-LC25-006, was completed to a depth of 915 m and intersected low-grade high-sulphidation copper mineralization.    Assays for this hole are pending.

John Miniotis, President and CEO, commented, “We are very excited to report this new copper discovery at La Coipita, highlighted by a substantial intercept of 114 m grading 0.70% copper within a broader intercept of 621 m grading 0.38% copper.  These results confirm the presence of a well-developed porphyry system with large-scale potential.  With drilling fully-funded and operated by Teck, we believe this discovery represents a major step forward in unlocking the value of this underexplored district, which is located in a major copper belt.   We look forward to updating the market as additional assays are received and the broader potential of the project is further evaluated.”

“We are encouraged by these early drill results from the La Coipita project. As we look to further advance exploration at the project, Teck is building a greater presence in the region and we continue to focus on growing strong relationships with local communities and suppliers, including those in and around Calingasta and San Juan,” said Stuart McCracken, Vice President, Exploration at Teck.

La Coipita Project Overview

La Coipita is a district-scale property covering over 70,000 hectares in the western San Juan Province, adjacent to the Chilean border.  Elevation across the property ranges between 3,500 and 4,500 MASL with moderate to high relief.  

The property lies within the prolific Miocene porphyry-epithermal belt of Argentina and Chile, host to numerous world-class deposits, including Filo del Sol, Los Azules, El Indio, Veladero, Pascua Lama and El Pachon.

In 2024, Teck completed 2,476m of diamond drilling in five holes, along with geophysical surveys and target mapping.   The 2025 drill campaign marks the second year of the earn-in program.   To date three additional holes have been drilled, DDH-LC25-006, 007 and 008, completing 3,523m, with assay results pending for 007 and 008.

Note:  All results in this news release for La Coipita rounded. Assays are uncut and undiluted. Widths are drilled widths, not true widths. True widths cannot be determined based due to the uncertain geometry of mineralization.

QA/QC and Core Sampling Protocols

Reference materials were inserted at a rate of 1 in 20 samples (5%), which included 33 Blanks, 33 Standards and 32 Duplicates (taken as a ¼ of the core). Cores were cut into two halves, one half stored in core boxes and the other half collected at 2m intervals, representing 50% of this drilled section, and sent to the ALS Lab in Mendoza, Argentina
